Overview: Inline Heavy-Duty Texture Airless Gun

The Graco 245820 Inline Heavy-Duty Texture Airless Spray Gun is built for high-production texture and coating work. Its straight-through body and oversized flow path minimize restriction when spraying thicker materials like drywall mud, primers, and elastomerics. Rated to 4000 psi (280 bar) with a robust 1/2 in. NPT(f) inlet, it pairs with large-frame texture sprayers for all-day reliability.

Compatible Machines

Fits Graco texture-capable airless rigs that meet the gun’s 4000 psi rating and use a 1/2 in. NPT(f) hose connection (adapter may be required for some setups). Common matches include:

Graco TexSpray Mark IV (Electric Airless Texture Sprayer)
Graco TexSpray Mark V (Electric Airless Texture Sprayer)
Graco TexSpray Mark X (High-output Electric Airless Texture Sprayer)
Other high-output Graco airless rigs that support 1/2" NPT(f) and up to 4000 psi

Frequently Asked Questions

If your machine supports up to 4000 psi and uses (or can adapt to) a 1/2" NPT(f) hose connection, the gun will fit. It’s a common match for TexSpray Mark IV, Mark V, and Mark X units. Check your hose ends and pressure ratings before use.

No—there is no internal filter. This helps prevent pack-out with heavy materials. Use pump strainers, manifold filters, or screened hoppers as needed for your application.

It ships with a RAC 5 SwitchTip & guard. Choose orifice sizes that match your material and desired flow; texture compounds often require larger orifices than standard architectural coatings.

Prime with the correct viscosity, keep hose runs as short/large-bore as practical, and clean immediately after use—especially with texture mud. Inspect seals and trigger movement regularly for smooth operation.
